Summary
Completed in 1940, this dam has a height of 30 feet and a length of 250 feet, with a storage capacity of 26 acre-feet. Situated on the TR-North Fork Willow Creek, this structure is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is inspected, permitted, and enforced by state authorities.
Despite being categorized as a low hazard potential structure, K and L Mcdowell #7 currently holds a "Not Rated" condition assessment. The dam has not been evaluated for its emergency action plan preparedness, and there is no information available on the risk assessment or management measures in place. With no recent inspection date provided, it is unclear whether the structure meets modern safety guidelines or has undergone necessary maintenance to ensure its continued functionality and safety for surrounding communities.
Located in the Omaha District and under the jurisdiction of Congressional District 00, Montana, K and L Mcdowell #7 stands as a pivotal water resource for the region. As climate change continues to impact water availability and quality, it is important for stakeholders and authorities to prioritize the evaluation and maintenance of such critical infrastructure to ensure the resilience and sustainability of water resources in the face of a changing climate.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
